A fiber block segment suitable for controlling erosion and stabilizing soil is
described that comprises an elongated fiber block formed of a densely packed elongated
thick fibrous material. The fiber block is wrapped with a fabric around three sides
so that the fabric defines a top anchor portion and a bottom anchor portions extending
from the block. The fiber block is securely attached to the wrapped fabric by another
fabric or twine spanning the fourth side of the block. Additionally, the fabric
is wrapped only up to the edges defining one end (a male end) and beyond the edges
defining the opposite end (the female end) to define a pouch-like structure at
the female end. The fiber block is made of coconut fibers (coir). The fabric is
woven from coir twine, and coir twine secures the fabric to the fiber block.
